* =============================================================================
*
* The CS4248 DSP used is pin and software compatible with the AD1848.
* I also have one of these cards with a CS4231. The driver talks to the
* emulated card as if it was a CS4231 and I still don't know how to tell the
* drivers to see the CS4248. The CS4231 more advanced features are NOT used,
* just the new input/output channels. Apparently some drivers are hardcoded
* for one or the other, so there is an option for this.
*
* There is lots more to be learned form the Win95 drivers. The Linux driver is
* very straightforward and doesn't do much.
*
* Recording and voice modes in the windows mixer still do nothing in 86Box, so
* this is missing.
*
* There is a jumper to load the startup configuration from an EEPROM. This is
* implemented, so any software-configured parameters will be saved.
*
* The CD-ROM interface commands are just ignored, along with gameport.
* The MPU401 is always enabled.
* The OPL3 is always active in some (all?) drivers/cards, so there is no
* configuration for this.
*
* Tested with DOS (driver installation, tools, diagnostics), Win3.1 (driver
* installation, tools), Win95 (driver auto-detection), lots of games.
*
* I consider type 0x11 (Washington) to be very well tested. Type 0x0C (Clinton)
* wasn't fully tested, but works well for WSS/Windows. BEWARE that there are
* *too many* driver types and OEM versions for each card. Maybe yours isn't
* emulated or you have the wrong driver. Some features of each card may work
* when using wrong drivers. CODEC selection is also important.
*
* Any updates to the WSS and SBPROV2 sound cards should be synced here when
* appropriate. The WSS was completely cloned here, while the SBPROV2 tends
* to call the original functions, except for initialization.
*
* TODO/Notes:
* -Some stuff still not understood on I/O addresses 0x624 and 0x530-0x533.
* -Is the CS42xx dither mode used anywhere? Implement.
* -What are the voice commands mode in Win95 mixer again?
* -Configuration options not present on Aztech's CONFIG.EXE have been commented
* out or deleted. Other types of cards with this chipset may need them.
* -Sfademo on the Descent CD fails under Win95, works under DOS, see if it
* happens on real hardware (and OPL3 stops working after the failure)
* -There appears to be some differences in sound volumes bertween MIDI,
* SBPROV2, WSS and OPL3? Also check relationship between the SBPROV2 mixer and
* the WSS mixer! Are they independent? Current mode selects which mixer? Are
* they entangled?
* -Check real hardware to see if advanced, mic boost, etc appear in the mixer?
* -CD-ROM driver shipped with the card (SGIDECD.SYS) checks for model strings.
* I have implemented mine (Aztech CDA 468-02I 4x) in PCem.
* -Descent 2 W95 version can't start cd music. Happens on real hardware.
* Explanation further below.
* -DOSQuake and Descent 2 DOS cd music do not work under Win95. The mode
* selects get truncated and send all zeros for output channel selection and
* volume, Descent 2 also has excess zeros! This is a PCem bug, happens on all
* sound cards. CD audio works in Winquake and Descent 2 DOS setup program.
* -DOSQuake CD audio works under DOS with VIDE-CDD.SYS and SGIDECD.SYS.
* Descent 2 DOS is still mute but volume selection appears to be working.
* Descent 2 fails to launch with SGIDECD.SYS with "Device failed to request
* command". SGIDECD.SYS is the CD-ROM driver included with the sound card
* drivers. My real CD-ROM drive can't read anything so I can't check the
* real behavior of this driver.
* -Some cards just have regular IDE ports while other have proprietary ports.
* The regular IDE ports just have a option to enable an almost-generic CD-ROM
* driver in CONFIG.SYS/AUTOEXEC.BAT (like SGIDECD.SYS) and the onboard port
* is enabled/disabled by jumpers. The proprietary ones also have
* address/dma/irq settings. Since the configuration options are ignored here,
* this behaves like a card with a regular interface disabled by jumper and
* the configuration just adds/removes the drivers (which will see other IDE
* interfaces present) from the boot process.
* -Continue reverse engineering to see if the AZT1605 shares the SB DMA with
* WSS or if it is set separately by the TSR loaded on boot. Currently it is
* only set by PCem config and then saved to EEPROM (which would make it fixed
* if loading from EEPROM too).
* -Related to the previous note, part of the SBPROV2 emulation on the CLINTON
* family appears to be implemented with a TSR. It's better to remove the TSR
* for now. I need to investigate this. Mixer is also weird under DOS (and
* wants to save to EEPROM? I don't think the WASHINGTON does this).
* -Search for TODO in this file. :-)
*
* Misc things I use to test for regressions: Windows sounds, Descent under
* dos/windows, Descent 2 dos/windows (+ cd music option), Descent 2 W95 + cd
* music, Age of Empires (CD + Midi), cd-audio under Windows + volume,
* cd-audio under dos + volume, Aztech diagnose.exe, Aztech volset /M:3 then
* volset /D, Aztech setmode, mixer (volume + balance) under dos and windows,
* DOSQuake under dos and windows (+ cd music and volumes, + Winquake).
*
* Reason for Descent 2 Win95 CD-Audio not working:
* The game calls auxGetNumDevs() to check if any of the AUX devices has
* caps.wTechnology == AUXCAPS_CDAUDIO, but this fails because the Aztech
* Win95 driver only returns a "Line-In" device. I'm not aware of any other
* game that does this and this is completely unnecessary. Other games that
* play cd audio correctly have the exact *same* initialization code, minus
* this check that only Descent 2 Win95 does. It would work if it just skipped
* this check and progressed with calling mciSendCommand() with
* mciOpenParms.lpstrDeviceType = "cdaudio", like other games do. There are
* some sound cards listed as incompatible in the game's README.TXT file that
* are probably due to this.
